Do I need to keep all of those licenses used to open doors in the Refuge or can I just stuff them in a storage box?

You'll need to have them in your inventory in order to be able to use them. I'm not yet certain if I'll be able to implement it (the API might not support it), but ideally, the licenses would eventually be added to a new bag in the inventory so they won't take up any space in the regular inventory bag.

you should make them easy to obtain but not easy
